Is there a way to simply choose the filter and have it exclude everything BUT that filter? I went to filter DoTs and set it to include, but still got everything. I wonder if there is possibly a way to "include only" for filters. Unless I missed something.

Ah... an iPad. Just checked on my iPhone and I'm having a similar issue. It seems like the "Apply Filters" button isn't catching. But it works just fine in Safari on a desktop PC. I'll see if our lead developer can figure it out.
